| 摘要 | [Objectives] This study was conducted to purify mutton samples by gel permeation chromatography (GPC). [Methods] Fourteen organophosphorus pesticide residues in samples were qualitatively and quantitatively analyzed by gas chromatography-mass spectrometry (GC-MS) in selective ion scanning mode (SIM). [Results] The organophosphorus pesticide standard solutions showed good linearity in the mass concentration range of 0.1-10.0 μg/ml with correlation coefficients (r) not lower than 0.999, and the detection limits (S = 3N) ranged from 0.01 to 0.05 mg/kg. The average recovery values were in the range of 80.2%-99.7%, with relative standard deviations (RSDs, n=3) in the range of 1.8 %-6.3%, at the addition levels of 0.5, 1.0 and 2.0 mg/kg. [Conclusions] The method is simple, sensitive and accurate, and can be used for the determination of organophosphorus pesticide residues in mutton. |
